3800 vaccum, breather questions

[smug]

how much vaccum should I have with a zzp ic and running a breather? I am only seeing 10 inchs according to my auto meter gauage. After the trans is done I will be pulling the top of the engine apart again to install the aluminm LIM gaskets ported blower and WBS throttle body. With is setup I would like the get rid of the breather, anyone know how I can do this.

i thought zzp ICs retained the stock PCV function?
you can switch to a catch can but i dont think that is what your asking or route your going to want to take, but it gets rid of the breather

They retain the function the pcv valve but because the core is large it blocks the passage or air going from the s/c to the lower intake. Whats the catch can thing?

route tubing from a drilled oilcap to a bottle much like the coolat overflow bottle
but this would not elimante it only git rid of the breather and leave it functioning the same, this is required by tracks for tech on licensed vehicles. is there a reason you are trying to get rid of it

I dont care for the breather, I want a fully functional pcv system, just like the factory.

I also just found a vac leak that has been haunting me forever. I have a pin hole leak in the BBV at the orange diaphragm thing. Ill spend the $150 at the dealer for a new one.

So I installed the new BBV and at idle the valve keeps opening and closing. Under boost it seems fine. If i unplug the small vac line going to the small electical thing under the BBV it will function as normal. I am now pulling 13 inch of van undle idle and it i hold the rpm at 1500 or higher it will have 15 inches of vac. SO something still id not right here and i have no clue where to start looking.

I've modified them to retain the stock function, but it's not really a DIY project. It requires the plates to be drilled, epoxied, and surfaced.
